The Petroleum Quality Institute of America (PQIA) is an independent resource for information and insights on the quality of lubricants in the marketplace. Our mission is to serve the consumer of lubricants by randomly sampling and independently testing lubricants taken from the field. Test results are posted along with the brand names on the PQIA website. This webpage provides an analysis on the brand detailed below.

The following are the test results for the sample examined.

Test Results and Assessment:

The additive levels in this sample indicate the product may not be suitable for use in the majority of automobile engines currently on the road. The detergent levels are substantially below that typically seen in engine oils meeting current API specifications. In addition, the high level of silicon (66ppm) in the sample tested indicates the product may be contaminated with abrasives.

This product does not claim compliance with any API specifications and displays no certification marks, making it impossible for consumers to compare to their engine manufacturer's requirements.

Note: Although laboratory tests alone cannot be used to establish if engine oil meets an API Service Category, they can be used to determine if it doesn't.
